* gdb.base/help.exp: Adjust following some spelling corrections
in GDB.
Since gdb sets up a nice sysroot path for us by default, automatically
pass it down to the sim target so it too gets a good default. This does
not override anything the user explicitly specifies of course.

This is just a minor cleanup of an ARI violation. As this affects

exercised.
